Why Medical Professionals Are Buzzing About PTFE Tubing: The Backbone Material for Smooth, Durable, and Composite Catheters
You might not realize it, but many familiar medical devices—like injection needles, catheter linings, and polypectomy snare outer tubes—share a common core: a high-performance polymer called PTFE(Polytetrafluoroethylene).
Depending on the processing method and dispersion medium, PTFE’s performance envelope can vary widely. At ECO, we’ve chosen the type best suited for medical single-lumen tubing.
PTFE: More than just a “fluoropolymer”
PTFE is renowned for its low friction coefficient, excellent biocompatibility, chemical resistance, and extreme inertness—earning it the nickname “the noble material of polymers.”
Based on production methods and dispersion medium, PTFE is typically classified into three types
Category | Suspension PFE | Dispersion PTFE | PTFE Emulsion |
Physical Form | White powder granules | White powder granules | Milky liquid (PTFE particles dispersed in water) |
Particle Size | Large (20–500 μm) | Medium (0.2–0.5 μm) | Very small (0.05–0.3 μm) |
Processing | Molding, sintering, ram extrusion | Paste extrusion, film sintering | Coating, dipping, spraying
|
Typical Uses | Seals, valve seats, thick-walled tubes, gaskets | Micro tubing, sintered microtubes, cable insulation | Lubricant coatings for catheters, fabric/metal coating |
Water/Emulsifier Content | No | No | Yes (contains water + emulsifier) |
Medical Use | Rare, mainly industrial (e.g., push tubes) | Catheter liners, infusion/drug delivery tubing, stents, artificial organs | Coating only, not used for standalone tubing (e.g., PI films + PTFE coating) |
At ECO, we use dispersion PTFE sourced exclusively from Daikin Japan, offering stable quality, excellent processability, and performance that meets the stringent requirements of medical manufacturing: cleanliness, dimensional consistency, and chemical resistance.
Why PTFE Tubing is Essential in Medical Applications:
PTFE single tubing is a cornerstone in medical devices, delivering unmatched performance in:
· Injection needles (inner/outer tubes) and polypectomy snare outer tubes.
· Thin-walled PTFE tubing, widely used for catheter linings, insulation, smooth gliding, and precise flow control in advanced devices like electrophysiological and energy-based catheters.
· Etched PTFE tubing, ideal for composite catheter linings.
